Bug #69003 [Opn->Nab]: RecursiveIteratorIterator breaks after removing directories on disk

Edit report at https://bugs.php.net/bug.php?id=69003&edit=1 ID: 69003 Updated by: requinix@php.net Reported by: elproducer20 at gmail dot com Summary: RecursiveIteratorIterator breaks after removing directories on disk -Status: Open +Status: Not a bug Type: Bug Package: SPL related Operating System: Ubuntu14, Debian7 PHP Version: Irrelevant Block user comment: N Private report: N New Comment: You're recursing SELF_FIRST: the parent will be examined before its children are retrieved. If you delete the parent then PHP won't be able to get the children. Go CHILD_FIRST. Previous Comments: ------------------------------------------------------------------------ [2015-02-07 08:00:45] elproducer20 at gmail dot com Description: ------------ I think this is similar to this bug - https://bugs.php.net/bug.php?id=55468 except I'm trying to delete directories but not sure why this happens. If i remove the line "rmdir(...)" then script completes successfully printing all empty directory names to output. Once the line "rmdir(...)" is added back, it breaks with the below stack trace. I worked around this by saving all directory names, then removing directories after the foreach loop completed. Test script: --------------- function deleteAllEmptyUserDirectories($path){ $iterator = new RecursiveDirectoryIterator($path); $iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS); // Get directories only $directories = new ParentIterator($iterator); // Loop over directories and remove empty ones foreach (new RecursiveIteratorIterator($directories, RecursiveIteratorIterator::SELF_FIRST) as $dir) { // Count the number of "children" from the main directory iterator if (iterator_count($iterator->getChildren()) === 0) { rmdir($dir->getPathname()); echo "[ DELETE ] " . $dir->getPathname() . "\n"; } } } deleteAllEmptyUserDirectories("/home/me/somedir/content"); Expected result: ---------------- [ DELETE ] 0 | /home/me/somedir/content/test [ DELETE ] 0 | /home/me/somedir/content/test2 Actual result: -------------- [ DELETE ] 0 | /home/me/somedir/content/test PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(/home/me/somedir/content/test): failed to open dir: No such file or directory' in /home/me/www/scripts/deleteAllEmptyUserDirectories.php:18 Stack trace: #0 [internal function]: RecursiveDirectoryIterator->__construct('/home/me...', 4096) #1 [internal function]: RecursiveDirectoryIterator->getChildren() #2 /home/me/www/scripts/deleteAllEmptyUserDirectories.php(18): RecursiveFilterIterator->getChildren() #3 /home/me/www/scripts/deleteAllEmptyUserDirectories.php(27): deleteAllEmptyUserDirectories('/home/me...') #4 {main} thrown in /home/me/www/scripts/deleteAllEmptyUserDirectories.php on line 18 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69003&edit=1
